Gout-mimicking sarcoma recurrence at a prosthesis bone interface remote from any joint.

Gout is known to occur in a variety of organs but most commonly presents as an inflammatory arthropathy. A few reported cases have documented its occurrence in prosthetic neo-joints or juxta-articular to this. We present the first reported case at a bone prosthesis interface remote from any joint and mimicking sarcoma recurrence because of its unusual location.
